I want to display Blogger widget only on label pages. I search on Google, but haven't found any way to do it. How to do it?
To display widget in all label pages use this condition
<b:if cond='data:blog.searchLabel'>
<!-- all label pages -->
</b:if>
To display widgets in a specific label page
<b:if cond='data:blog.searchLabel == "foo"'>
<!-- for label 'foo' -->
</b:if>
